> .... since all the drives, cables and controllers are identical, I'm trying to figure out if there is something *else* I should be looking into for why smart would have an issue, but the rest of the OS has no issues with these drives. (zfs is storing data, reports them all as online, etc). I looked into the smartctl code, and there definitely is a carve out for FreeBSD 8.1 or later, but I don't know enough about the new internals to know if the is any kind of concern parsing more than 10 drives, etc.
Use smartctl -h to get a usage summary
$ sudo smartctl -d atacam -i /dev/ada11
smartctl 5.39.1 2010-01-28 r3054 [FreeBSD 8.0-STABLE amd64] (local build)

Also, out of curiosity, are you using the ahci(4) driver or the siis(4)
Thank you - fantastic!
I tried the -d atacam before I sent the email, but I obviously specified it incorrectly because I wrote the message anyway. This solves the issue, not sure why it can't detect it.
To answer your follow up question, I started using just siis, but added ahci to allow ahci functions. As far as I can tell, AHCI functions add on top of the SIIS ones. The boot compact flash (not on the SIIS card) converted to ada from ad once ahci was loaded.
